如何对电站锅炉进行安装

2018-03-07 05:48:24 PM

  电站锅炉是我国火力发电的主要方式之一,是给人们提供电源的方法之一,是非常重要的,电站锅炉,通俗来讲就是电厂用来发电的锅炉,那么,如何对电站锅炉进行安装呢?今天我们就和大家一起来解答一下:

  大型电站锅炉安装:主要有前墙布置、前后墙对冲布置和四角布置。按前两种方式布置时,一般采用旋流式燃烧器,其优点是煤粉管道布置较简单,但不宜用于低挥发分和高灰分的燃料。

  四角布置就是把直流式燃烧器布置在炉膛四角,其喷口中心线与炉膛中心的一个假想圆相切。四角布置的缺点是风道布置较复杂,但燃烧比较稳定,它适用于多种燃料。

  电站锅炉的本体结构类型主要取决于燃料特性、锅炉容量和蒸汽参数等因素。常见的有倒U型、塔型和箱型。

  倒U型适用于各种容量的锅炉和燃料,故应用广泛。锅炉的高度比其他炉型低,受热面布置较方便,风机和除尘设备都可放在地面上,但占地面积较大。

  塔型适用于燃用多灰烟煤和褐煤的锅炉,无转弯烟道,可减轻飞灰对受热面的局部磨损,且占地面积较小。但炉体高,安装和检修较复杂。

  箱型适用于容量较大的燃油和燃气锅炉,其优点是结构紧凑,占地面积较小,锅炉与汽轮机的连接较方便。缺点是制造工艺较复杂,检修困难。

  以上就是对如何对电站锅炉进行安装的简单介绍,希望这些知识能够帮助大家。

  Power station boiler is one of the main ways of thermal power generation in China. It is one of the methods to provide power to people. It is very important. The power station boiler is, in general terms, the boiler that the power plant uses to generate electricity. So, how to install the power station boiler? ? Today we will work together with everyone to answer:

  Installation of large-scale power station boilers: There are mainly front wall arrangements, front and rear wall hedging arrangements, and four-corner arrangements. When arranged in the first two ways, swirling burners are generally used. The advantage is that the pulverized coal pipeline arrangement is relatively simple, but it is not suitable for low volatile matter and high ash fuel.

  The four-corner arrangement is to arrange the DC burners at the four corners of the hearth, with the centerline of the spout tangent to an imaginary circle in the center of the hearth. The disadvantage of the four-corner arrangement is that the air duct layout is more complicated, but the combustion is relatively stable and it is suitable for a variety of fuels.

  The type of the main body structure of a power station boiler depends mainly on factors such as fuel characteristics, boiler capacity, and steam parameters. Common inverted U-shaped, tower and box.

  Inverted U-type for a variety of capacity of the boiler and fuel, it is widely used. The height of the boiler is lower than that of other furnaces, and the heating surface is arranged more conveniently. Fans and dust removal equipment can be placed on the ground, but the floor space is large.

  The tower type is suitable for boilers burning more bituminous bituminous coal and lignite, and there is no turning flue, which can reduce the local abrasion of the fly ash on the heated surface and has a small footprint. But the furnace is high, installation and maintenance more complicated.

  The box type is suitable for large-capacity fuel and gas boilers. Its advantages are compact structure, small floor space, and convenient connection between the boiler and the steam turbine. The disadvantage is the manufacturing process is more complex, maintenance difficulties.

  The above is a brief introduction on how to install the power station boiler, I hope this knowledge can help everyone.
